AI Technical Summary

Technical Problem

Existing brake disc testing devices cannot simultaneously perform friction and high temperature tests, and brake discs are inconvenient to fix, with unstable manual control of friction force, resulting in inaccurate test results.

Method used

The design employs a combination of fixed and friction components, utilizing a first and second motor to drive the rotating shaft and bidirectional threaded rod to achieve rapid fixing and stable friction of the brake disc. The friction resistance performance is tested using an electric push rod and friction blocks.

Benefits of technology

This technology enables stable fixing of brake discs and accurate testing of their friction resistance, improving the accuracy and efficiency of the testing.
